HI ALL FROM THE UK I HAVE A A4 1.9TD1 (98) IT HAS CENTRAL LOCKING AND IVE BEEN TOLD I CAN ADD A REMOTE JUST BY BUYING THE HAND SET HAVING A KEY CUT AND PROGRAMMING IT DOES ANYONE KNOW IF THIS IS TRUE IN THE UK THERE ARE 2 SPECS OF THE A4 AVANT SE AND OBVIOUSLY NON SE ON THE SE REMOTE DOOR LOCKS ARE NOT ALWAYS STANDARD

 

I'm not sure about in the UK, but in the States all A4's came equiped after 97. Do you happen to know anyone who owns a similar year Audi with the remote? You could always program it to your car to verify if you have remote locking installed.
